I purchased this six months ago, audio and noise cancellation are fairly decent but the mic for phone conversations is terrible

Perfect for music, outstanding noise cancellation considering the shape of ear plugs

You can use this adjust volume up/down as well as adjust noice cancellation

This is not a major issue for me but for those who need the best noise cancellation, they should consider QC35.

These headphones are a disappointment, but I purchased to replace lost Bose QC 20s, which were corded but AMAZING in battery life and much better noise cancellation.

They do not seem to be designed for pure noise cancellation, and so people wanting maximum cancelation should look at the Quiet Comfort segment of the Bose line

but I may have to start looking into other brands, which is sad because the adjustable noise cancellation is EXACTLY what I had been wishing for in a pair of earbuds, and the Bluetooth feature was icing on the cake!!

The adjustable noise cancellation works amazingly well and it is very easy to adjust through the app or the buttons on the wire

You also need to remember to turn off the auto timer if you're using it for pure noise cancellation

Comfortable, great sound, unbelievable noise cancellation...CAN still hear others around me, if you want to completely shut out noise these won't be great, but they do a fantastic job reducing most noise and making it easier to concentrate in our open office environment.

I brought great noise cancellation headphones with inner ear buds and thin wireless head set from another brand

In my opinion, shared by many, BOSE has the BEST noise cancellation in the market, if noise cancellation is your top priority you must definitely go with BOSE.

The adjustable noise cancellation actually had to be set near the middle to effectively squelch the drone of my treadmill

I bought these for my office environment and all day headset, decent noise cancellation with Bluetooth to be able to move around to the other workplaces while on the line with a customer

Maximum noise cancellation dangerous on motorcycle, does poor job suppressing high speed wind buffeting sounds but great

I think that feature alone allows the earpieces to stay in my ears tighter, thus allowing for better noise cancellation

If you're having second thoughts about buying these due to fears about ineffective noise cancellation - like I did - I can assure you that those fears are unwarranted.

Also very poor noise cancellation, so i no longer will be purchasing Bose products

The two primary issues that other reviewers have been having seem to be 1) poor call quality, and 2) bad noise cancellation

The reason I bought these is because they are in ear and have adaptive noise cancellation, meaning that they actually let you choose how much of your surroundings you choose to cancel out.

Adjustable noise cancellation is welcome but a nuisance to modify, at 100% is nullifies a lot of noise.

The sound and noise cancellation are great, but it is awkward to operate

Fit under full face helmet, adjustable noise cancellation levels, great everyday performance in regular non riding use

I think I am going to keep these because of the excellent sound quality and good noise cancellation

All have great noise cancellation and sound

Noise Cancellation:Fantastic

From the few hours that I have been using these for I am amazed at how well the adaptive noise cancellation works, I will definitely be using these for bike

Personally I would highly prefer less battery time to gain higher quality noise cancellation if that is the trade-off

Perhaps it is partly due to that history, plus reading all the negative reviews on the NC on the QC-30s, that I was not expecting great noise cancellation

Incredible sound with amazing noise cancellation.

Comfortable, great sound, unbelievable noise cancellation...CAN still hear others around me, if you want to completely shut out noise these won't be great, but they do a fantastic job reducing most noise and making it easier to concentrate in our open office environment.

Some with good noise cancellation, some without.

great noise cancellation and comfortable fit

I purchased these because I travel quite a bit for work, and was look for a wireless solution with good noise cancellation

BUT the main reason I purchased them is so that I can appropriately make calls on work when I am at coffee shops and other places where I need to both hear the other person clearly (noise cancellation) and have the other person hear me.

I wasn't sure of the purpose of adjustable noise cancellation until I tried it on a plane.

Here's why:1) poor noise cancellation

Dropping it one or two clicks allows very good cancellation without that unnatural sound.

The adjustable noise cancellation is a feature I enjoy quite a bit - on a flight, it's max level, of course.

Amazing noise cancellation, comfortable for hours, decent sound quality.

The slight inconvenience of having a wire is far outweighed by the significantly better noise cancellation

The Bose QuietControl 30 has good noise cancellation and decent audio quality for listening to music, but the overall usability is poor

I came from QC35 headphones which despite having superior noise cancellation felt uncomfortable to wear at times

The QC30 came up with adjustable Noise cancellation

I love the earpieces, they provide better noise cancellation that the bulky headphones

Pros: - Excellent noise cancellation compared to other earbuds - Excellent retention in ear - Convenient neck band supports earbuds even when not in the ear - Ability to connect to more than one device - Adjustable cancellation level allows adjusting for maximum cancellation or allowing some background so you may converse with others without removing earbuds - Ability to answer and hang up calls from device without touching phoneCons

Perfect noise cancellation and sound quality that rivals my over the ear QC 35 headphones

Great noise cancellation for the platform - you're not going to get the same as you would with the over-the-ear style, but that's the sacrifice for this form factor.

I know that it is one of the most expensive of its kind, but I got to give "thumbs up" for the sound quality and also specially for noise cancellation feature which works better than any other ones that I have tried so far

Excellent noise cancellation and sound quality

Sound and noise cancellation are great but as an overall product, I hate them

I did a lot of research and decided to purchase these based on the fact that these have 12 different adjustable noise cancellation levels

Noise cancellation good for my frequent airline travels

I bought these hoping that the QC30 earphones would have better noise cancellation than the QuietControl 25 earphones I already have, but the QC30 earphones were not as good.

You won't even miss the noise cancellation

That's not to say that in some circumstances I would really like noise cancellation but there are pros and cons to each

I know that it is one of the most expensive of its kind, but I got to give "thumbs up" for the sound quality and also specially for noise cancellation feature which works better than any other ones that I have tried so far

The Audio Quality and Noise Cancellation for listening to music or watching movies on your device is really good.

Pros: Great sound, excellent noise cancellation , very long battery lifeCons: Absolutely terrible call quality

I purchased the QC 30 from my local Bose store a few days ago and have already been using them during my daily commutes on the DC Metro as well as in the office (where I sit in a cube farm next to some loud salespeople on the phones all day).

These earbuds cancel the noise but not as good as an over the ear headset.

You will see some examples in my video of that as well as in a store and road noise

As others have noted, the noise cancellation is not as good as with the Quiet Comfort 35 - which I would use more often if they weren't also earmuffs.

Guess I can just switch to the phone for my limited voice call use (or maybe Bose will issue a

I like this a lot as you don't have to take off the headphones and then put back on--you can just detach the earbuds and let 'em dangle until you need to stick 'em in your ear again

I travel and these are as good as

Before, I used Jabra Elite 65T because it has "hear through" feature that allow ambient noise to go thru so I could hear both music and conversation

Also of note, when they broke I contacted Bose and they replaced them for free, no questions asked
